Hi,
For this question, we are given the following system of equations:
2x - y = 3
x + y = 3
Let's make the first equation in the form of y = mx + b as shown below:
y = 2x - 3
x + y = 3
Now, substitute the first equation into the second to get:
x + 2x - 3 = 3
Combine similar terms to get:
3x = 6
x = 2
We now know that x = 2 and can plug this value into one of the given equations to get:
2 + y = 3
y = 1
FINAL ANSWER: x = 2 ; y = 1
I hope that helps you out!
Answer:
The equation of the line would be D) y - 7 = -3(x -5)
Step-by-step explanation:
In order to find this, we must first start with the base form of point-slope form.
y - y1 = m(x - x1)
Now we put the slope in for m and the point in for (x1, y1)
y - 7 = -3(x - 5)
Answer:
m ≤ 60 (look at the picture)
Step-by-step explanation:
<em>5 greater than m is no more than 65</em>
m + 5 ≤ 65 <em>subtract 5 from both sides</em>
m + 5 - 5 ≤ 65 - 5
m ≤ 60

Answer:
As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.
